Question

安装el-get的说明如下：

;; Copy/paste this code into your *scratch* buffer,
;; hit C-j, and you have a working el-get.
(url-retrieve
 "https://raw.github.com/dimitri/el-get/master/el-get-install.el"
 (lambda (s)
   (goto-char (point-max))
   (eval-print-last-sexp)))

当我这样做时，名为*Backtrace*的缓冲区会在debugger-mode中打开，其中包含以下内容：

Debugger entered--Lisp error: (void-variable closed)
  eval(closed nil)
  eval-last-sexp-1(t)
  eval-last-sexp(t)
  eval-print-last-sexp()
  (lambda (s) (goto-char (point-max)) (eval-print-last-sexp))(nil)
  apply((lambda (s) (goto-char (point-max)) (eval-print-last-sexp)) nil)

我认为文件https://raw.github.com/dimitri/el-get/master/el-get-install.el中有错误吗？或者还有什么我必须设置才能使这样的脚本工作？

Answer 1

不知何故，下载的文件会附加closed行，原始文件中不会出现这一行 - 不知道为什么，它不会发生在我身上。它在回溯的最后可见。

您可以复制整个el-get-install.el文件，粘贴到*scratch*并使用C-j进行评估。

在Emacs 24.3中安装el-get来管理软件包
